Return true if the mask interleaves one or more input vectors together.
I.e. <0, LaneLen, ... , LaneLen*(Factor - 1), 1, LaneLen + 1, ...> E.g. For a Factor of 2 (LaneLen=4): <0, 4, 1, 5, 2, 6, 3, 7> E.g. For a Factor of 3 (LaneLen=4): <4, 0, 9, 5, 1, 10, 6, 2, 11, 7, 3, 12> E.g. For a Factor of 4 (LaneLen=2): <0, 2, 6, 4, 1, 3, 7, 5>
NumInputElts is the total number of elements in the input vectors.
StartIndexes are the first indexes of each vector being interleaved, substituting any indexes that were undef E.g. <4, -1, 2, 5, 1, 3> (Factor=3): StartIndexes=<4, 0, 2>
Note that this does not check if the input vectors are consecutive: It will return true for masks such as <0, 4, 6, 1, 5, 7> (Factor=3, LaneLen=2)

◆ isOneUseSingleSourceMask() [1/2]
|
inlinestatic |
Return true if this shuffle mask represents "clustered" mask of size VF, i.e.
each index between [0..VF) is used exactly once in each submask of size VF. For example, the mask for VF=4 is: 0, 1, 2, 3, 3, 2, 0, 1 - "clustered", because each submask of size 4 (0,1,2,3 and 3,2,0,1) uses indices [0..VF) exactly one time. 0, 1, 2, 3, 3, 3, 1, 0 - not "clustered", because element 3 is used twice in the second submask (3,3,1,0) and index 2 is not used at all.

◆ isSelect()
|
inline |
Return true if this shuffle chooses elements from its source vectors without lane crossings and all operands have the same number of elements.
In other words, this shuffle is equivalent to a vector select with a constant condition operand. Example: shufflevector <4 x n> A, <4 x n> B, <undef,1,6,3> This returns false if the mask does not choose from both input vectors. In that case, the shuffle is better classified as an identity shuffle.

Return true if this shuffle mask chooses elements from its source vectors without lane crossings.
A shuffle using this mask would be equivalent to a vector select with a constant condition operand. Example: <4,1,6,undef> This returns false if the mask does not choose from both input vectors. In that case, the shuffle is better classified as an identity shuffle. This assumes that vector operands are the same length as the mask (a length-changing shuffle can never be equivalent to a vector select).

Return true if this shuffle splices two inputs without changing the length of the vectors.

This operation may also be known as a merge or interleave. See the description for isTransposeMask() for the exact specification. Example: shufflevector <4 x n> A, <4 x n> B, <0,4,2,6>

◆ isTransposeMask() [1/2]
|
inlinestatic |
Return true if this shuffle mask is a transpose mask.
Transpose vector masks transpose a 2xn matrix. They read corresponding even- or odd-numbered vector elements from two n-dimensional source vectors and write each result into consecutive elements of an n-dimensional destination vector. Two shuffles are necessary to complete the transpose, one for the even elements and another for the odd elements. This description closely follows how the TRN1 and TRN2 AArch64 instructions operate.
For example, a simple 2x2 matrix can be transposed with:
; Original matrix m0 = < a, b > m1 = < c, d >
; Transposed matrix t0 = < a, c > = shufflevector m0, m1, < 0, 2 > t1 = < b, d > = shufflevector m0, m1, < 1, 3 >
For matrices having greater than n columns, the resulting nx2 transposed matrix is stored in two result vectors such that one vector contains interleaved elements from all the even-numbered rows and the other vector contains interleaved elements from all the odd-numbered rows. For example, a 2x4 matrix can be transposed with:
; Original matrix m0 = < a, b, c, d > m1 = < e, f, g, h >
; Transposed matrix t0 = < a, e, c, g > = shufflevector m0, m1 < 0, 4, 2, 6 > t1 = < b, f, d, h > = shufflevector m0, m1 < 1, 5, 3, 7 >
